Syntax of strongly typed enums wrongly implemented?

Question

I'm currently testing the November CTP for Visual Studio 2012 and came across an interesting problem: Is it mandated by the standard that for strongly typed enumerations the enum and struct/class keywords have to be in the same line or is that an error in the implementation that should be reported to Microsoft?

This compiles:

enum struct name : type { ...

This does not (C2332)

enum
struct name : type { ...

EDIT: as James suggested this is a bug in the implementation and was reported to Microsoft

`enum class/struct` doesn't require the NovCTP. So does this happen on the pure VC2012 release? — Nicol Bolas, Dec 01 '12 at 03:16
@NicolBolas: Just tried, the bug seems to be also in the RTM version of the compiler! — MFH, Dec 01 '12 at 11:04

Yes, this is undoubtedly a bug. Newlines are not significant after preprocessing.

This is tracked by the following issue on Microsoft Connect (To the OP: Thank you for opening this bug.):

Bug in implementation of strongly typed enums

If this bug is important to you, please upvote it on Microsoft Connect. Note that there is a trivial workaround: don't place a newline between the enum and struct keywords.

Would you post a link here to the bug, for future readers of this question? (And so I can track it.) Thanks! – James McNellis Nov 30 '12 at 23:06
Sure thing, I added the link to the question. – MFH Nov 30 '12 at 23:27

James, you're awesome. The way you actively track and file bugs is very helpful. Let me know when you need help fixing them. ;) – GManNickG Dec 01 '12 at 00:27
